The settings for CD00, which is also commonly used, were not provided, and they are somewhat different. This has caused some confusion for which I apologize. The following are the correct settings for firmware CD00. 1. Input external frequency in the EXTERN FREQ Menu. 2. AUTO-SWITCH N will not use internal oscillator if external frequency is lost. Y Will use internal oscillator if external frequency is lost, but will use external reference when available. 3. Under RCVR CTRL set Clock Steering to N The frequency and auto-switch settings should be saved through the power cycle by default.
